Go for the new Retina MacBook Air. You won’t be sorry!
It’s ridiculously thin and light. It’s snappy and handles everything I’ve thrown at it. It has a fantastic display and great speakers. Plus, you get Touch ID without the Touch Bar (personally not a fan). Mine has been absolutely flawless since I got it in November. The same goes for my girlfriends, and she’s really hard on her keyboard. Still, no issues at all.
Even if the keyboard would break, you would have four years of coverage. Four years!
I get the hassle of bringing in a computer for service. I’ve never had to and I’m hoping I never will, but still, I’d rather do that than deal with Windows everyday on my spare time. I’ve had win machines at work during the last three years and while it’s gotten a lot better, it’s still a pain at times. So many horrible upgrades that are forced upon the user at the most inconvenient times. Blue screens. App crashes. I can go on. Even something as simple as connecting/disconnecting external displays causes problems. Besides, even my premium Dell Quad Core i7 laptop workstation is way, way slower than my so-called “underpowered” MacBook Air in day to day use.
You might not need to worry about the keyboard, but you will have plenty of other issues with Windows.
